Some good news is that I think that the Service Pack mechanism is now fixed for sd-card installations, so in future you won't have to download a complete new sd-card image to upgrade, just a small PET package (PET is the native package format for Puppy Linux).
In theory anyway, I fixed it but haven't yet tested the fix. It should be OK.

A note about the download image, it is for a 8GB sd-card, or bigger. The reason I didn't release a 4GB image, is Quirky has a "snapshot" feature that needs lots of room. This feature is something that users have come to love. You can take a snapshot of a working system, then at any time in the future can choose to roll back to any earlier snapshot.

Which is great if you have broken the installation. Or, you compiled lots of packages, and just want to get rid of them all -- take a snapshot before doing all the compiling and you can just restore to it.

Quirky is designed so that any PET package can be uninstalled, and the system will go back to how it was before the PET was installed. If a newly installed PET overwrites an existing file, that file gets archived (look under /audit folder), and if the PET gets uninstalled, the archiveed file gets restored.

This mechanism is also supposed to work with Service Pack PETs, so in theory you could upgrade to a new version of Quirky, but if you don't like it, just uninstall the PET.

I say "in theory" because this roll-back hasn't had much testing.

Note, the aforementioned "snapshot" mechanism can also be used to roll back a version upgrade. Take a snapshot before installing the Service Pack. Snapshots are more tested.

I have to say sorry for resurrecting an old thread but i had to say Thankyou BarryK, finally gave me something worth running on my Pi (other than Raspbian). I thought Puppi was a lost cause but im glad you decided to make a working version we can use.

p.s. I still never did get that Pburn.pet working on Ubuntu no matter what i tryed XD
